I'm having trouble getting conditions correct. i've drilled four holes in top but now the temperature is all over the place. so is the humidity. i've tried stoppering each of the the holes but the humidity sky rockets. here is photo: here is top view (two fans on right lower; light bulb on upper right; R= Thermostat; light blue is water bowl and egg carton in middle. T = thermometer is mounted on right side of egg basket and just on top of basket): Here is side view (two fans on left (one upper pointed down and lower one pointed to just bypass light bulb b/c i can't angle it onto lightbulb with hardware wire in the way; light bulb on left, T=Thermometer on top of left side of egg basket; water bowl and R = Thermometer on right).
